'rYrE-wnmms MACHINE.

To all whom it may concern Be it known that I, Gannon A. SE11}, citizenof the United States, and resident of .ll'ion, in the county of Herkimerand State of New York, have invented certain new and useful Improvementsin 'lype-Writing Machines, of which the following is a specifi cation.

My invention relates to typewriting machines and it has for its objectto provide improved dead key mechanism for such machines. Specificallystated, the principal object of the invention is to provide, in a case.shift typewriter, means whereby one of the types on a type bar can printan accent mark, for example, whiclr requires no letter space, and theother type. on the same type v bar can print a character that doesrequire letter spacing, and that the escapement will he operated in onecase. position and not in the. other, the. ribbon vibrator, it present,be ing operated in both instances.

One form of my invention is illustrated in the. accompanying drawings,in which- Figure 1 is a partial front to rear section of a. typcwritingmachine having my inven tion embodied therein.

Fig. 2 is a fragmentary enlarged view of a portion of the same but withthe ribbon mechanism in operated position.

Fig. 3 is a rear elevation in section about on the, line of Fig. l.

Fig. l is a fragmentary plan view oi that portion of the mechanism whichis in the base. of the machine.

, I have shown my invention embodied in a. machine which in mostrespects is like the No. 10 Remington typewriter. The mainframe of thismachine. comprises a.base 1 from which rise posts 2 which support a topplate 3, and on said top plate there is a. carringof which I have shownin the drawing onl the roller platen l and feed rack 5. Said feed rackmeshes with a feed pinion (3 on the front end of a shaft. which at itsrear end carries an. oscapement wheel 7, said shatt, being journalcd ina. housing 8 mounted on the top plate 3. The escapcment wheel 7 iscontrolled by feed dogs 10 1nounted on a (log rocker 11 suitably pivotedin the stationary framework and having an arm 12, which is connected bya link 13 with an arm 14 mounted on a rock shaft 15, which is pivoted atits ends on pivot screws Specification of Letters Iatent.

16 secured to the side bars of the base 1. Said rock shaft 15 has arms17 projecting rearward therefrom. Fig. i, and, by means of links 18,supporting a universal bar '20. Said universal har lies beneath theprinting key levers oi the machine, t'our of which are partially shownin the drawings, three of these being special key levers 21 and thefourth an ordii'iary key lever 21. The rock shaft 15, being thusconnected to the univer sal bar, is operated by all of the ordinaryprinting keys and it may, therefore, be termed a universal member. Thekey levers 21 are pivoted. to a slotted plate 22 and are provided withreturning springs I have not deemed it necessary to show these keylevers in full because they arc' a part of the well-known Remingtonmachine.

In that machine each of said key levers has a depending lug consistingof a vertical having two types 26 and 26 thereon, which bars when one ofthe keys is operated are adapted to strike against the front face of theplatenl. In the normal position of the parts the lower one 26 of the twotypes strikes the platen and this is therefore the lower case type, andwhen theplaten is shifted upward the upper case type 26 strikes theplaten. The case shift mecha nism of the Remington machine comprises ashift rail 27, Fig. 1, on which runs a. roller or wheel mounted on theshiftable' platen frame of the machine-and said rail 27 can by means notherein fully shown, but which is shown in my prior Patent No. 1,203,795,dated November 7, 1916. Said railis carried by two irregularly-shapcdarms or brackets 28, and each of said arms or brackets is at its lowerend rear arm of a lever 31., Said levers are pivoted on a cross rod '32,each of them extending to the keyboard of the machine. where it providedwith a. case shift key 33; and the two levers 81 are con .ncctod by aheavy transverse bar 34 to cause v with said universal bar by priorpatent above referred to; but for the sake of simplicity I have hereshown more or less conventionally a vibrator 35 having its stem 36pivoted to the forwardly directed arm of a bell crank 37, which bellcrank is pivoted at 38 to a bracket 40 secured to the shift rail 27.Said bracket has an upwardly and forwardly extending arm terminating ina guide ll for the vibrator. The depending arm of the bell crank 37 isconnected by a link 42 with the upper end of a lever 43 of the firstorder, which is pivoted at 44 to lugs 45 projecting from the stationarypart"of the machine, these lugs in the No. 10 Remington projecting fromthe type bar segment 45. In Fig, 3 the lever 43 is shown as a built-upframe comprising two lever arms spaced apart and connected at theirlower ends by a cross rod 46. this being the form of lever employed inthe ribbon mechanism set forth in my said prior patent. In said patentthe link &2, bell crank 37 and bracket 40 are replaced by a morecomplicated mechanism adapted toprovide'for the use of a bi-color ribbonand for throwing the ribbon out of operation for mimeographing; and somesuch complete ribbon mechanism is preferably employed, although thesimpler form shown in this application can also be employed.

The rod 46 passes through an open-ended slot 47 in a lever 48, which ispivoted on a pivot screw 49 to the side of the arm 14. The lever 48 hasa rearwardly directed arm from which an ear 50 is bent off beneath thearm ll and through said arm 14 is screwed an adjusting screw 51 having alock-nut The lower end of said screw 51 is adapted to contact with theear 50 in such fashion that when the shaft 1.5 is rocked the arm 14 isthereby moved downward and the lever 48 partakes of the motion of saidarm 14 and moves the rod 46 toward the rear of the machine, thus movingthe upper end of the lever l3 toward the front of the machine andoperating the vibrator. The 1e ver 48 can be operated independently ofthe arm '14. however; said lever in such case turning about its pivot 49and being restored to its normal relation to said arm 14- by means of aspring 53; the construction in this respect being like that shown in myprior patent and at present employed in the No. 10 Remington machine.

' In order to operate the lever 48 and the ribbon mechanismindependently of the arm 14 and the esrapement mechanism, said lever 48is connected by means of a link 54 with a secondary universal bar 55supported at its ends by arms 56 which are pivoted on the cross rod Thelink 54 is connected means of a pin 57 passing through a slot 58 in abracket 60 secured to the universal bar 55 near the middle of themachine. The construction is such that it said universal bar 55 bedepressed the lever 48 will be operated; but if said lever be operatedby the universal bar :20 acting through the arm 14, the link 54 can movedownward without disturbing the universal bar Said universal bar 55 isprovided with returning springs (31 and with stops 62 which limit itsupward motion by contact with the base-frame.

In case it is desired to make any key a dead key the screw 2% of thatkey lever is either removed entirely or is screwed up so high that itwill not operate the universal bar 20, and underneath that same keylever another screw 63' is screwed up through the universal bar 55 intosuch position that a.

depression of said key lever will, through said screw, operate saiduniversal bar 55 and will thus operate the ribbon vibrator but not theeseapement. just described is that at in the Remington machine.

In order to provide for making any desired printing key a live key inlower case and a dead key in upper case, or vice versa, I removeentirely from that key lever the screw 24 and place beneath said keylevel one of the screws 63; and I provide means for connecting that keylever with the rock shaft 15 in one position of thecase shift mechanismand for disconnecting said key lever from said rock shaft in the otherposition of said mechanism. To this end'I replace the screw 24 with ascrew '64 having a. wide lat head (35 and I'pivot to the upper side ofthe rock shaft 15 a coupler, here shown as an arm or plate 66 a apted tobe turned in under the head 65 of the screw or to be turned to anotherposition away fromsaid screw head. Said plate or arm v66 has a hub 67through which passes a pivdt screw 68 screwed into the shaft 15- so asto allow the arm (36 to be turned in right and lefthaud directions, butso that in case said arm is depress-ml by the head 65 the shaft 15 willbe rocked to actuate the ribbon vibrator and the escapcmcnt in the samegeneral manner that it is rocked by the universal bar 20 when depressedby an ordinary printing key lever. If the arm 66 is not in register withthe screw head (35 then a depression of the key lever carrying the screwhead will fail to-rock the shaft 15 and the cscapement will remain atrest. But at this stroke the .ribhon vibrator will be actuated throughthe screw 63, secondary universal bar 55, link 54, lever 48 and frame43.

The arm 66'can be connected with the ease shift mechanism in variousways, the means here shown consisting of a wire 70 pa. 'ing through ahole in the arm (36 andat its upper end secured to a rightanglcd bra-ket 71 secured, as by screws 72, to one of he shift brackets 28. In thepresent instance the wire is shown threaded and provided The arrangementpresent employed with two nuts'73, one on each sideof the bracket 71.The wire 70 is bent near its lower end as shown at 70 in. Fig. 3 so thatwhen the platen is in lower case position the part of the wire thatprojects beneath the plate 66 is inclined toward the right and when theshift key is operated and the bracket 28 is moved upward this wire isdrawn throughthe plate 66 and cams said plate toward the right. WVhilein the present instance the wire is bent at its lower end toward theoperators right so that when the case shift key is depressed the plate66 will ,he swung toward the operators right it will be swung out fromunder the screw head and be understood that said wire may be bent towardthe left to swing the plate toward the left, if desired. As hereinshown, this particular plate66 18 at the extreme left-hand side of themachine and in the lower case position of the platen it extends straighttoward the rearibf the machine with its rear free end lying beneath thehead ()5 of the screw (Bl. In this position of the plate its associatedkey 21 is la live kev; but if the case shift key be de )ressed thisplate will be swung off to the oiservers left and will in that positionof the parts this willbe a dead key and at that time'the eseap'ementwill not be operated. The type barthat is operated by this key will havean ijaccent mark "on it for printing in the uppercase position and someother character that re quires letter spacing for lower case posit-lOIl.5

In case it is desired to have several of these keys av screw-64 and acoupler 66 are provided for each such key. and the several couplers canall be operated byone wire 7 O. In the present instance, I have shownassociated with three keys three of the coupler plates 66 all connectedtogether by a link or JHI' 74 pivoted to each of said plates as by apivot screw 75. The construction is such that when one of said plates isswung towand the right or toward the left by the shift mechanism theremaining plates will also be swung in the same direction.

It will be understood that any key equipped in this way can be madeeither normally live or normally dead. .-In Fig. 4 I have shown two keysnear the right-hand side of the figure arranged to be normally live keysand to be dead keys in the upper case position; and I have also shownanother key near the middle of the machine which is a. dead key in thelower case position and a live key in the upper case position. The lastmentioned key lever has its plate 66 normally. inclined toward theobservcrs right and out of the path of the screw head 65. If the caseshift key be operated and all of the plates 60 be swung toward the leftin Fig. 4 the two said plates at the righthand side of the figure will bmoved into inoperative position and the one near the middle of thefigure will be moved to operative position. The arrangement can bevaried at convenience. It will also be understood that in the samemachine there can be one or more keys that are dead in both case shiftpositions. Such a key lever would not be provided with any plate--66 butwould be made aidead key in the same manner as heretofore, namely, bywithdrawing the screw 24 and placing beneath said key lever one of thescrews (33.

In the operation of the machine the action of the ordinary keys will beas usual heretofore. The two special key levers shown at the right-handside of Fig. 4 are connected to type bars, each of .which has a lowercase type 26 adapted to print some" nism being in normal position, thelower case character will be printed, the universal bar will bedepressed, and the rocker 15,

will be operated by means of one of the cou-- I plers 66, which couplerwill be depressed the screw head 65; and the operation of said rockerwill work the escapenient to feed the carriage. When one of the uppercase or accent types is used the shifting upward of the frame 28 andwith it the wire or cam :70 willshift the coupler 66 toward the observers left in Fig. L out from under the screw head 65. The depressionof the printing key will then result in printing the accent and in anoperation of the ribbon vibrator through the instrumentality of thespecial universal bar 55, but the rocker 15 and the escapement mechanismwill not be operated.

Fig. 4 is connected with a type bar whose lower case type 26 is anaccent or other mark that does not require letter spacing and whoseupper case type 26 prints some character that does require letterspacing. If

this key lever be depressed when the case shift mechanism is in normalposition the universal bar 55 and the ribbon vibrator will be operated,but the escapement will not be operated, the coupler 66 being out ofregister with the screw head 65; but if the platen be moved to uppercase position this coupler will be swung to the left underneath saidscrew head and a depression of this key at that time will result notonly in an operation of the ribbon. vibrator but also in an operation.of the rocker 15 and of the cscapcment mechanism.

V arious changes can be made in the deout departing from my invention.
